Description

Detergent providing apparatus of the washing machine

The present invention relates to a detergent supply apparatus for a washing machine, and more particularly, to a detergent supply apparatus for a washing machine in which detergent and water are mixed and evenly sprayed onto laundry.

In general, a washing machine is a device for washing laundry through a process of washing, rinsing, and dehydrating to remove stains on clothes, bedding, etc. using the action of detergent and water.

The washing machine is difficult to determine the amount of detergent when the detergent is directly put into the washing tank, and because the laundry is easily discolored, a separate detergent supply device is installed at the upper part of the washing machine so that the water supplied to the washing tank together with the detergent.

1 is a cross-sectional view showing the internal structure of a conventional washing machine, Figure 2 is a cross-sectional view showing a detergent supply operation of the washing machine according to the prior art.

In the conventional washing machine, as shown in FIG. 1, an outer case 2 that forms an exterior and a rotary blade 3 that is disposed inside the outer case 2 to accommodate laundry and form a washing stream are formed inside. A washing tank 4 installed at a lower portion thereof, a storage tank 6 which is suspended between the washing tank 4 and the outer case 2 by the support member 5 in the outer case 2 and accommodates the washing water at the same time; A motor 8 disposed below the water storage tank 6 to generate a driving force for rotationally driving the rotary blade 3 or the washing tank 4; and a driving force of the motor 8 to the rotary blade 3 and the washing tank. And a power train 9 for selectively supplying to (4).

The top cover 10 having the laundry input hole 11 is mounted above the out case 2.

The top cover 10 is provided with a door 12 for opening and closing the laundry input hole 11, and a water supply device 14 for supplying the water supplied into the washing tank (4).

The water supply device 14 is a water supply valve for intermitting the water supplied through the external hose 15 and the water supply passage for supplying water to the detergent container 19 to be described later connected to the water supply valve 16 ( 17).

One side of the water supply device 14 is provided with a detergent supply device 18 for supplying a detergent with water.

As shown in FIG. 2, the detergent supply device 18 includes a detergent container 19 disposed below the water supply path 17 to contain detergent, and a detergent container housing 20 in which the detergent container 19 is installed. It is configured to include.

Reference numeral 30 is a drain valve, and reference numeral 32 is a drain hose.

Referring to the operation of the washing machine according to the prior art configured as described above are as follows.

First, the laundry is put into the laundry input hole 12 of the top cover 10, the detergent is put into the detergent container 19, and then the detergent container 19 is pushed into the detergent container housing 20, the detergent container 19 ) Is inserted into the detergent container housing (20).

Then, when the door 12 is closed and the washing machine is operated, water supplied through the external hose 15 is dropped into the detergent container 19 through the water supply valve 16 and the water supply passage 17. .

The water dropped into the detergent container 19 is mixed with the detergent, flows down into the detergent container housing 20, and then falls into the washing tank 4.

At this time, the water falling into the washing tank 4 is dropped to the predetermined width (w) in the water supply passage 22 to wet some of the laundry, gradually filling the interior of the washing tank 4 and the water storage tank (6) do.

When the water mixed with the detergent rises to a predetermined level of the water storage tank 6 and the washing tank 4, the motor 8 is operated to rotate the rotary blade 3 or the washing tank 4, the laundry is detergent It will work with the water mixed with it, causing the contamination of the laundry.

When the washing stroke is completed, the contaminated water is drained to the outside through the drain valve 30 and the drain hose 32.

After the drainage operation is completed, the water supplied to the washing machine through the external hose 15 is dropped through the water supply valve 16 into the detergent container 19.

The water dropped into the detergent container 19 is dropped to the predetermined width (w) in the water supply passage 22 to wet some of the laundry, and gradually fills the inside of the washing tank 4 and the water storage tank 6. .

When the water mixed with the detergent rises to a predetermined level of the water storage tank 6 and the washing tank 4, the motor 8 is operated to rinse the stroke while rotating the rotary blade 3 or the washing tank 4 in progress. do.

When the rinsing cycle as described above proceeds for a predetermined time, the draining operation as the washing stroke proceeds, and after that, dehydration is performed and washing is finished.

However, the detergent supply device 18 of the washing machine according to the prior art is not soaked quickly in the laundry because the detergent and water mixed in the detergent container 19 is concentrated down to a predetermined width (w) soaking only a part of the laundry, laundry There is a problem that can be discolored.

In addition, when the water supplied to the detergent container 19 is biased toward the front and rear or left and right, there is a problem that the detergent is left in the wall or the corner of the detergent container 19, so that the detergent of the quantity cannot be used for washing.
